| In specialized literature, reports on anatomy of miners in host plants are few in number. These agents trigger excavations, or paths, by consumption of plant inner tissues by larvae of several insects. The aim of this work was to investigate leaf miner occurrence in Commelina diffusa (a cosmopolitan plant) and Floscopa glabrata (an amphibious plant) using anatomical techniques. The place where the plants were collected is subjected to seasonal floods, consequently both the species were exposed to the same weather conditions and seasonal floods. This study showed that members of Agromyzidae and Chironomidae families, which are Diptera endophytophagous larvae types, were responsible for the tunnels. Moreover, in Commelina diffusa Agromyzidae larvae were... |

| Este estudo avaliou a qualidade das águas do córrego Vargem Limpa e testou a hipótese de que trechos protegidos, do sistema aquático, localizados no interior de uma unidade de conservação, favorecem a preservação da diversidade de Chironomidae (Insecta: Diptera). Foram realizadas amostragens em quatro pontos e algumas variáveis físicas e químicas da água foram aferidas. Os resultados, obtidos com o estudo, indicaram o predomínio de gêneros associados a substratos arenosos e que os trechos protegidos pela unidade de conservação apresentaram melhor qualidade ambiental, com diversidade de Chironomidae mais preservada, demonstrando a importância destas áreas na manutenção da diversidade de Chironomidae. |

| No presente estudo a dieta de Aspidoras fuscoguttatus Nijssen & Isbrücker, 1976 foi analisada em exemplares procedentes de 18 riachos da região noroeste do estado de São Paulo, sistema do Alto Rio Paraná. Foram analisados os conteúdos gástricos de 246 indivíduos, com o registro de 26 tipos de itens alimentares e predominância de itens autóctones. Destes, larvas de Chironomidae, Simuliidae e Ceratopogonidae foram os mais importantes, mas a contribuição de detritos, tecamebas e fragmentos de vegetais variou de acordo com as características dos riachos. Enquanto em águas mais claras os itens alimentares podem ser visualmente selecionados pelos peixes, em águas mais turvas essa seleção pode ocorrer. Assim, a habilidade da espécie em obter recursos em... |

| Jururumberus n. gen. is erected based on the males of J. arapuca n. sp. from São Paulo State, in southeastern Brazil and J. uatuma n. sp. from the Amazonas in northern Brazil. The genus can be separated from other Orthocladiinae based on the combination of bare eyes, wing, and squama; frons U-shaped, extended ventrally; AR ≤ 0.3, antenna without apical seta; palp short, five-segmented, with sensilla clavata in subapical sensillum coeloconicum; no acrostichals; costa strongly extended; R4+5 ending proximal to M3+4; anal point narrowly triangular with microtrichia only, sitting high on tergite IX; and virga composed of two spines. |

| The purpose of this work was to verify the benthic macroinvertebrates community responses through environmental factors along a headwater tropical reservoir. Samplings were taken with a Van-Veen grab along the reservoir in littoral and profundal regions and in the headwater, next to the dam and the middle of the reservoir. Samples were taken during both wet and dry seasons. Dissolved oxygen concentrations, electric conductivity, temperature and pH near the sediment have been performed in situ, at every sampling station by using a multiprobe and Secchi disc. Total water phosphorus and chlorophyll a concentrations were analyzed to determine the trophic state index. Sediment's organic matter, total phosphorus, nitrogen concentrations and granulometric... |

| Five lotic systems of Serra do Cipó, south-east Brazil, were investigated in order to assess the existing diversity of benthic macroinvertebrates, habitats-microhabitats, and the available trophic resources. For each river it was analysed the communities of benthic macroinvertebrates and the composition of some taxonomic groups (Plecoptera, Ephemeroptera, Trichoptera and Diptera Chironomidae): the community with Bivalvia Sphaeriidae, Oligochaeta and Ephemeroptera Baetidae (being supposed a closed relation Bivalvia-Oligochaeta based on the process of bioturbation and enrichment of sediment in organic matter) in Tanque River; the macrofauna associated to aquatic macrophytes from rivers Peixe and Preto do Itambé reflecting the reaction of the ecosystems... |
